Answer:

a. y = 1.5x

Step-by-step explanation:

Both equations are equations of a line. All options have the form:

y = a*x

where y and x are the variables and a is the slope.

The slope of the equation corresponding to machine B is less than the machine A's slope (machine A line is above machine B line). The only option in which the slope is less than 3 is y = 1.5*x.

The correct answer is y = 1.5x, A.
I am sure it is because I took the K12 test. I used the answer from the other person that answered this, and got it wrong. I reviewed the test, and It says that 1.5x is correct.

If f(x)=3x and g(x)= x + 4

bogdanovich [222]

Answer:

$f(g(1))=15$

Step-by-step explanation:

$f(x)=3x\\g(x)=x+4\\f(g(1))$

First, you need to evaluate $g(1)$ :

$g(1)=(1)+4\\g(1)=5$

Now, you plug this into $f(x)$ and evaluate $f(5)$ :

$f(5)=3(5)\\f(5)=15$

Now you know $f(g(1))=15$ .

Find the area of the kite. The figure is not drawn to scale.

aleksandrvk [35]

Answer:

The area of the kite is $42\ units^{2}$

Step-by-step explanation:

we know that

The area of a kite is half the product of the diagonals

so

$A=\frac{1}{2}(D1*D2)$

we have

$D1=2*(3)=6\ units$

<em>Find the length side of diagonal D2</em>

Applying the Pythagoras Theorem

$D2=\sqrt{5^{2}-3^{2}} +10\\ \\D2=4+10\\ \\D2=14\ units$

<em>Find the area of the kite</em>

we have

$D1=6\ units$

$D2=14\ units$

substitute

$A=\frac{1}{2}(D1*D2)$

$A=\frac{1}{2}(6*14)=42\ units^{2}$
